I recently reinstalled my computer and installed Linux Subsystem which I always do. When I wanted to run composer I noticed something strange. It failed because it was unable to establish a TLS connection.
[RuntimeException] Failed to clone https://github.com/inquam/colors.php via https, ssh protocols, aborting.

Please make sure you have the correct access rights and the repository exists.
After trying a bit more I noticed that this happens no matter which GitHub repository I try to clone via https and it also applies to any connection via curl or other commands that connect using TLS. I have tried several proposed solutions in other threads like updating ca-certificates, reinstalling Ubuntu on Windows 10, downloading https://curl.haxx.se/ca/cacert.pem and pointing to that in php.ini, making sure ipv6 is not the preferred method in Ubuntu etc.
Previously when I have used Ubuntu in Windows 10 I have just installed and everything has worked without any issues like this at all.
Update: After testing a bit more I decided to test install the Windows version of GIT and remove the Linux one since the Linux Subsystem can now run Windows binaries. It worked fine. Then Composer wanted to download https://packagist.org/packages.json and failed once again due to TLS. So TLS doesn't work in Bash when running Linux versions of the programs but work fine with WIndows versions.
[Composer\Downloader\TransportException] The "https://packagist.org/packages.json" file could not be downloaded: Failed to enable crypto failed to open stream: operation failed
To demonstrate it seems to affect every native Bash application I tested the following too
me@DATHREADRIPPER:/mnt/e/src$ php -r 'echo file_get_contents("https://packagist.org/packages.json");'
PHP Warning: file_get_contents(): Failed to enable crypto in Command line code on line 1 PHP Warning: file_get_contents(https://packagist.org/packages.json): failed to open stream: operation failed in Command line code on line 1
Update: For me, this was finally solved when I installed the newer Ubuntu 18.04 in Windows from the Windows store.
